- to which it appertains to make and use the same.

This invention relates to loading devices 7 and particularly to that type used in conmany purposes.

neotion with the charging 0 coke ovens, although it will be understood by those versed in the art that the device may be used for Heretofore it has been difficult to obtain the exact amount of coal to be fed to the ovens and considerable trouble and loss has been entailed by manufacturers on this account, first by not giving enough coal in the oven, and second, by giving too much, the latter being more serious as the charge would not be burned ofi in time and the use of the oven would be lost for from between forty-eight to seventy-two hours, as the case might be.

The object of the invention is to avoid this difliculty and to insure the same amount of coal being fed to the lorry each time the charge is drawn.

The further object of the invention is the provision of means for permitting the telescoping receptacle to remain in normal position until the coal has stopped running by 7 reason of its having filled the receptacle, at which time the gate is closed and automatically held in this position until again operated.

With the foregoing and other objects in view, the invention consists of certain novel features of construction, combination and arran ement of parts, as will be more fully 'dcscri ed and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a side elevation partly in section of the measuring device in open position; Fig. 2 is a similar view in closed position.

Referring more especially to the drawing,

1 represents the track which leads from be-- neath the coal bins to the top of the coke ovens and which is adapted to support the lorry 2 from one point to the other. The,

coal bin is represented at 3 having a chute 4 leading to the spout 5. This spout comprises a series of telescoping sections and a bottom open section 6 which is provided with a cross bar 7 to be hereinafter described.

The upper section of the spout is connected to the bottom of the trough and has sliding therethrough a gate 8 which is provided on its outer end with a rack bar 9 adapted to be engaged by a pinion 10 on the operating shaft 11. A suitable pulley 12 driven by a chain 13 from the driven plnion 14 is connected to the shaft 11 so as to drive the gate 8 in either direction. The opposite end of the gate has connected to it a rod 15 having upon its outer end a ring 16 which surrounds a chain 17, passing over the pulleys 18 and 19, the latter being located upon a cross bar 20 bridged across the chute below the gate.

- The chain 17 is provided with an adjustable clamp 16 which is adapted to be engaged by the ring 16 so as to lower the inner end of the chain 21 which engages with the cross bar 7 of the bottom section 6 and the opposite end of the chain is connected, to a counter-balance weight 22 for a purpose to be hereinafter described.

A suitable pawl 23 is pivoted upon a suitable support and has its end engaging teeth formed upon the wheel 18 and its opposite end formed in a ring 18 surrounding the chain 17. v

In operation, when it is desired to fill the telescoping spout, the pinion 14 is turned in any suitable manner as by crank or power and the gate 8 drawn to the osition shown in Fig. 1, when the coal wi start to flow from the chute into the spout. Simultaneously with this action, the ring 16 engages the clamp 16*, draws u the weight 22 and permits the lowering o the sectlons of the spout. The weight holding the clamp against the ring 16 prevents further movement of the spout and after the coal has filled the same,it stops running and the gate is now closed across the openin When the ring 16 contacts with the ring of the pawl 23, its engaging end is release from the ratchet, the weight drops and the telescoping sections 5 are pulled up to normal position when the operation may be repeated. By adjusting the clamps the sections may be lowered in the lorry to any determined degree. 7

From the foregoing description taken in connection with the accompanying drawings,

the construction and operation of the invention Will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction .may be resorted to without departing from the prin ciple or sacrificing any of the advantages of the invention, as defined in the appended claims.

I claim as my invention 1. In a device of the class described, a hopper, a chute leading therefrom, a telescopic spout, means for controlling the opening thereto, means for collapsing said spout, means to positively hold said collapsing means inoperative, and means to trip said holding means when opening is closed.

2. In a device of the class described, the combination with a hopper, of a chute leading therefrom, a telescopic spout adapted to receive material from said chute, a sliding ate closing the opening from the chute to t e spout, means for supporting the sections of said spout, means for returning said sections to normal, means for holding said returning means inactive, and means carried by the gate for tripping said holding means when the gate is fully closed.

3. In a device of the class described, the combination with a hopper, of a chute leading therefrom, a telescopic spout supported by the hopper, a manually operated gate for closing the connection between said chute and spout, adjustable means for supporting the sections of said spout, means for raising the sections of said spout, means for holding said raising means inactive, and means carried by the gate' for tripping said holding means when the gate is fully closed.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
